/ Best spikes for mixed road/ice

As title suggests, need spikes which go over regular running shoes.
Mostly road running with icey/snowy patches. I imagine most types would wear out pretty quickly but this snow and ice is not going anywhere for a while and I need to get out. <pokes fat belly>

Yaktrax are better if you are likely to encounter roads too and dont want to keep taking them off.

You will see what I mean when looking at the two products. I have both and love them both for their relatively different applications. They are both comfortable and easy to use over trainers and trail/fell shoes.

Doubt the Yaktrax will last as long, but cheaper, and on sale I think with Go Outdoors right now.
